Silane (SiH4)

Technical Parameters

Silane musanganiswa wesilicon nehydrogen. Iri izwi rinoshandiswa kune zvakatevedzana zvemakomponi, kusanganisira monosilane (SiH4), disilane (Si2H6) uye mamwe epamusoro-level silicon-hydrogen makomisheni. Pakati pavo, monosilane ndiyo inonyanya kuzivikanwa, dzimwe nguva inonzi silane kwenguva pfupi. Silane igasi risina ruvara rine hwema hunosemesa hwegariki. Soluble mumvura, inenge isinganyungudike mu ethanol, ether, benzene, chloroform, silicon chloroform uye silicon tetrachloride. Iyo kemikari zvimiro zve silanes zvinoshanda zvakanyanya kupfuura alkanes uye zviri nyore oxidized. Kupisa kunongoerekana kwaitika kana wasangana nemhepo. Iyo haiite nenitrogen iri pasi pe25 ° C, uye haiite nemakomisheni ehydrocarbon pane tembiricha yekamuri. Moto uye kuputika kwe silane mhedzisiro yekuita neokisijeni. Silane inonzwa zvakanyanya kune oxygen nemhepo. Silane ine imwe concentration ichaitawo zvinoputika neoxygen patembiricha ye -180°C. Silane yave inonyanya kukosha gasi rinoshandiswa mu semiconductor microelectronics maitiro, uye rinoshandiswa mukugadzirira akasiyana mamicroelectronic mafirimu, anosanganisira single crystal films, microcrystalline, polycrystalline, silicon oxide, silicon nitride, uye metal silicides. Iyo microelectronic applications ye silane ichiri kukura zvakadzika: yakadzika-tembiricha epitaxy, selective epitaxy, uye heteroepitaxial epitaxy. Kwete chete kune zvigadzirwa zvesilicon uye silicon yakasanganiswa maseketi, asiwo yekomboni semiconductor zvishandiso (gallium arsenide, silicon carbide, nezvimwewo). Iyo zvakare ine maapplication mukugadzirira superlattice quantum tsime zvinhu. Zvinogona kutaurwa kuti silane inoshandiswa munenge ese epamberi akabatanidzwa emagetsi ekugadzira mitsara munguva dzazvino. Kushandiswa kwesilane sesilicon-ine firimu uye coating kwakawedzera kubva kune yechinyakare microelectronics indasitiri kuenda kune akasiyana minda sesimbi, michina, makemikari uye optics. Imwe nzira inogona kushandiswa ye silane kugadzirwa kwepamusoro-kushanda kweceramic injini zvikamu, kunyanya kushandiswa kwe silane kugadzira silicide (Si3N4, SiC, nezvimwewo) teknolojia ye micropowder yakakwezva zvakanyanya uye zvakanyanya kutarisa.

Application:

① Zvemagetsi:

Silane inoshandiswa kune polycrystalline silicon layers pasilicon wafers pakugadzira semiconductors, uye sealants.

②Solar:

Silane inoshandiswa mukugadzira solar photovoltaic module.

③Maindasitiri:

Inoshandiswa muGreen-saving Green Girazi uye inoshandiswa kune vapor deposition yakaonda firimu maitiro.

Normal package:

Advantage:

①Anopfuura makore gumi pamusika;

②ISO mugadziri wechitupa;

③Kutumirwa nekukurumidza;
